A new methodology for dealing with the Electric-Magnetic Anti-skid Braking System (EMABS) and recycling the regenerating energy on braking is proposed. Developing a dynamic damper which comprising positive and negative type resistors connected in series becomes a fast switch with adaptation, attenuation and fast recovery system properties, is a crucial turnkey. For braking purpose, the most general configuration is to couple the fast switches to the stator and rotor coils in an AC alternator that is driven by the vehicle's wheels or propellers. After performing the dynamic impedance matching in this braking system, the EMABS effect and recycling of the regenerating energy on braking are accordingly obtained.
